Authorization variables in SAP BW/4HANA are used to dynamically restrict data access based on user-specific criteria, such as organizational units or regions. These variables are particularly useful in query design and reporting. Below is a detailed explanation of why the correct answers are A and B:
Correct: Authorization variables can be used in query filters to dynamically restrict the data displayed in a query. For example, you can use an authorization variable to filter sales data based on the user's assigned region. This ensures that users only see data relevant to their authorization profile.
Option A: In the definition of a query filter
Correct: Authorization variables can also be used in characteristic value variables. These variables allow you to dynamically determine the values of characteristics (e.g., customer, product, or region) based on the user's authorization profile. This is particularly useful for creating flexible and secure reports.
Option B: In the definition of a characteristic value variable
Incorrect: Authorization variables cannot be used in the definition of calculated key figures. Calculated key figures are mathematical expressions that operate on existing key figures and do not involve dynamic filtering based on user authorizations.
Option C: In the definition of a calculated key figure
Incorrect: While restricted key figures allow you to filter data based on specific criteria, they do not support the use of authorization variables. Restricted key figures are static and predefined, whereas authorization variables are dynamic and user-specific.
Option D: In the definition of a restricted key figure
